(arms- 225) The present invention relates to new. and usefu1- improvements in syringesof a type adapted I primarily for injecting mineral oil into the rectum of a person for treating the lower bowel,

and. the invention has for its primary object to provide a transparent container adapted to contain a predetermined quanity of the oil so that site sides of which is fixedly attached the forked the quantity of oil discharged from the syringe .v

' may be ascertained and also forproviding a connection for a rubber bulb to the tubefor the purpose of supplying the necessary press'ure toeject the fiuid therefrom andarranged so that the liquid will not come 'into contact with the "bulb. A' further important object of the present -in-- vention is to provide a handle for the'transpa'r- V ent container and forming a support for the under the'hook 2i and rubber bulb, the handleand bulb beingarranged for simultaneous gripping by the hand of a A still further formance, relatively inexpensive to 'manufacture and otherwise well: adapted for the purposes for which the same is intended.

Other objects andadvantages reside in the details of construction and Ioperation as more fully hereinafter described and claimed, referencebe ing had to the accompanying drawing forming part hereof, wherein like numerals refer to 'Figure 1 is a side elevational view of a embodying my invention, and

Figure 2 is a fragmentary elevational view of. the lower .end of the transparent tube or container for the oil.

Referring now to the drawing indetail, the numeral 5 designates a glass tube or container adapted to contain a predetermined quantity of object isrto provide a device of this character-0f simple and practical constr-uction, which is efii'cient and reliable'in perends 18 of a wire handle I9 by soldering or other suitable method of; attaching, the outerend of the handle, being formed with a substantially J1 wing-like portion within which the bulb I6 is adapted to rest. Thering 20 is of substantially oval form and of a size slightly less'thanthat of the'bulb'lB sothatthe bulb will notpassf g through the ring. The forked portion l8 extends downwardly from thehandle member. I9

andfipr ojecting upwardly from the handle is a hook member 2| adapted to engage .over the (91113613 to prevent ejection ofJ-the cork from the tube 5 by pressure created therein by the bulb.

Inorder to remove thecork for refilling the tube 5, the cork is turned to move the tube l3 from v I the cork may then be withdrawn from the tube When u singmineralv oil or similar substances in a syringe of this character it is important to prevent, theoil from entering the rubber bulb,

as the latter rapidly deteriorates from contact with the oil. Accordingly, this objection; is

in an upright position to determine the amount of oil discharged therefrom. The device isintended for the self-administering of m'ineral'oil by way of the rectum. When: using the syringe; the tube'5 is'filled with mineral oil to the desired level and the nozzlel0 inserted in therectum, the handle l9 and bulb I6 being grasped a syring'e avoidednby providing the connection between the tube of oil'and the bulb as above described.

The handle enables the tubeof oil to be held so as to hold the tube inan upright positionin front of the patient in order that the volume of oil fed from the tube may be observed.

The upper end of the glass tube is 'fiared as shown at II and adapted for receiving a cork or stopper I2'tightly fittedtherein.

. One end of a rigid tube i3 passes through the cork for communication with the interior of the tube 5, the other end of the tube" l3 having a section of flexible tubingv l4 attached thereto for;

connecting the nozzle end 15 of a' rubber bulb I6 to the cork or stopper.
